Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding tool for documents or the like used when binding a plurality of sheets or documents.

[0002]

2. Description of the Related Art Conventionally, a stapler is used to bind a plurality of sheets or documents.

[0003]

In the conventional method for binding a document or the like using a stapler, since a staple needle made of a metal material is used, it cannot be used without the staple needle,
When a document bound with a staple is no longer needed and shredded with a shredder, the shredder has a drawback that the shredder blade is damaged unless the staple is removed.

In view of the above-mentioned conventional drawbacks, the present invention has been made.
An object of the present invention is to provide a binding tool for documents and the like that can bind a plurality of documents and the like by the same operation as that of the conventional stapler without using a staple made of a metal material.

The above and other objects and novel characteristics of the present invention will become more fully apparent when the following description is read in view of the accompanying drawings. However, the drawings are for explanation only and do not limit the scope of the present invention.

[0006]

In order to achieve the above object, the present invention has a base plate and an insertion recess for inserting a document or the like to be bound between the base plate and the tip of the base plate. A guide plate fixed on the base plate, a pressing plate rotatably supported by a rear end portion of the base plate so as to cover the upper part of the guide plate, and constantly urges the pressing plate upward. As described above, an urging spring provided between the pressing plate or the guide plate or the base plate, and a tip end portion fixed to the guide plate side at a portion near the tip end portion of the pushing pressure plate is provided. A binding piece forming blade that forms a substantially U-shaped binding piece with an acute angle, and a binding formed by the binding piece forming blade that is constantly urged to rotate in the storage direction inside the binding piece forming blade near the tip end thereof. Bending-out cam for pushing out a piece and the binding piece A binding piece insertion groove forming blade having a binding piece insertion hole in which the binding piece fixed to the pressing plate so as to be located at a rear portion of the blade is inserted by the binding piece pushing cam, and the pressing plate is the base. Provided in the blade insertion groove formed in the guide plate and the base plate into which the binding piece forming blade and the binding piece insertion groove forming blade when the plate is pressed, and the blade insertion groove of the guide plate When the pressing plate is pressed against the base plate, the binding piece pushing cam is rotated, and the binding piece formed by the binding piece insertion groove forming blade is used as the binding piece insertion hole of the binding piece insertion groove forming blade. A cam operating pin that is inserted into a binding device constitutes a binding tool for documents and the like.

[0007]

With the binding device for documents and the like configured as described above, the documents and the like to be bound are inserted into the insertion recesses for the documents and the like between the base plate and the guide plate. When the pressing plate is pressed against the base plate in this state, the binding piece forming blade first forms a U-shaped binding piece on the inserted document and the binding piece insertion groove forming blade forms the binding piece insertion groove, Thereafter, the binding piece pushing-out cam abuts on the cam operating pin and rotates, pushing out the binding piece and pushing it into the binding piece insertion hole of the binding piece insertion groove forming blade. When the pressing force of the pressing plate is released in this state, the pressing plate is rotated upward by the urging force of the urging spring, and the binding piece pushed into the binding piece insertion hole of the binding piece insertion groove forming blade is pushed into the binding piece insertion groove. The documents are bound by passing through the sheet and protruding upward. From this state, the documents and the like are pulled out from the insertion recesses of the documents and the like, whereby the document binding work is completed.
